fix: NsxResource.executeRequest DeleteNsxNatRuleCommand comparison bug

Fixes an issue in NsxResource.executeRequest where Network.Service
comparison failed when DeleteNsxNatRuleCommand was executed in a
different process. Due to serialization/deserialization, the
deserialized Network.Service instance was not equal to the static
instances Network.Service.StaticNat and Network.Service.PortForwarding,
causing the comparison to always return false.
